Its personality trait says it is strongly defiant, which means that Sp. Def. is its best IV stat, but why is the stat so low? Could it have been something that happened while battling?

I my humble opinion you could increase its sp. def with the energy drink Zinc although best case u will only get a 10 or so increase, u could consider giving it a Rowap berry so then if people take advantage of the low stat u can inflict damage on them.

if u use energy drinks reduce other high stats with berry to add the differance on to sp. def
